[MEncoder-users] Zero check failed in ifo_read.c:328

Hi,

What does your message have to do with the "XBOX 360 transcode" thread?

FYI, you have replied to a message in that thread instead of sending a new
one, causing your (unrelated) mail to appear as a reply in that thread.
This is bad netiquette. Please don't do that in the future.

Why do you think anything is wrong?

AFAIK this message is harmless. I've seen it numerous times while playing
some DVDs and observed no ill effects.

I see no problems here.

There should be a science of discontent. People need hard times and
oppression to develop psychic muscles.
